I like it. I think simplistic interfaces are the way to go for collaborative/social apps.
The downside of course is that it's dead easy to clone these simple apps (like Twitter, TinyURL, etc.), which means the barrier to entry for your competition is quite low. This effect has been recently amplified with the boom in quality frameworks and dirt cheap infrastructure (EC2, App Engine).
The end result is that making a killer web app is not enough and you instead have to make sure you nail the social marketing of it and build up a large enough userbase that the brand/userbase becomes the real value.
First, that Kindle killer isn't even close to existing.
Second, if you think $400 is steep for a device that has a 1 second refresh rate and a gray-scale screen, just wait until you see the price tag on 10" of full-color, touchscreen, iInk.
Third, and the real barrier to entry, Amazon has the bookstore to back it up. You can make the finest e-book reader in the world, but until you have "magic" wireless delivery and a limitless library to back it up, it's considerably more inconvenient to use than the Kindle.
Apple will not crack this space. It will have to be Google or Microsoft.
What Microsoft offered was the Microsoft Passport->.NET Passport->Windows Live ID. The difference being that under their plan, Microsoft was the only provider. Big difference.
OpenID allows people to use whichever services they want as their OpenID providers.
As recent switcher, I have to say I mostly agree. Macs still freeze and lock up and do weird shit, but at least you don't have to run on the antivirus/antispyware treadmill like you do with Windows. That alone makes a Mac worth it for me.
Of course, I scooped up mine when it was a deal on Amazon. I could never justify paying full sticker price...
I think I'm going to sue Apple because the of the "I'm a Mac" ads. Do you know how difficult life has become for short, chubby people since that ad campaign came out? It's horrible.
At what point do people realize that being a subscriber to someone with more than a few thousand followers basically just means you've put yourself on their "super short press release mailing list".
Twitter has got to be the wet dream of publicity agents and direct marketers alike...
My cheaper version: Stand in my own filthy gray water and then leave it overnight. Problem solved. Of course now I have to solve this jock itch on my feet...
$15K for a car that seats two, gets 38 MPG, and will vanish into a singularity in the event of a crash is anything but smart.
